Words from George:

Storm coming? High winds and heavy rains can damage your roof and lead to water intrusion in your home, requiring costly repairs to both your roof and your interior space. Prepare your home for minimal damage by installing spray foam insulation. Properly installing spray foam insulation in your roof provides the biggest defense against wind uplift as your home becomes significantly more structurally sound. Spray foam insulation is designed to increase the integrity of your home by tightly bonding to all surfaces which helps keep your home intact during severe weather.
Additionally, the proper installation of spray foam insulation will provide a monolithic membrane that seals your attic and prevents water intrusion even though the exterior roof substrate may get compromised. It is especially important in the installation process to ensure all roof penetrations are identified and sealed completely. Spray foam insulation can give you peace of mind in stormy weather.
And guess what? You’ll save up to 30% on your energy costs, too!!

We hear the term "building envelope" frequently, but some do not know the true here it is!

A building envelope includes all the components that make up the shell or skin of the building. These components separate the exterior of the building from the interior, and are designed by the project architect or engineers to meet the needs of each individual application. The building envelope may also be defined as the components that separate conditioned areas from unconditioned space. Exterior or unheated living spaces are not included inside the envelope, while any living space that is equipped with heat or air conditioning would be included. The building envelope must be carefully designed with regard to climate, ventilation, and energy consumption within the structure. 08/21/2015

What is Spray Foam Insulation?

Spray Foam Insulation is the alternative to traditional building insulation such as fiberglass. Air will move in and out of your home through every crack and crevice, making your HVAC system work overtime. Roughly one third of air infiltrates through your walls, ceiling, and floors as well. Our AirTight™ Spray Foam will form a continuous isolation and air sealing barrier on your walls, roofs, around corners and other hard to reach surfaces leaving no open spaces for air or bugs.
This all happens once the foam liquids are mixed as they react quickly when introduced to oxygen. The foam will expand 5 to 10 times its original size filling gaps and crevices, creating an airtight seal on the structure. Your home is then moisture locked to prevent mold and mildew from entering and spreading inside your home. AirTight™ SprayFoam Insulation can maximize a homeowner’s investment by sealing the building envelope to stop conditioned indoor air from escaping and prevent unconditioned air from entering a home. Having an AirTight™ Spray Foam home also has other benefits as well such as the reduction of allergens entering the home allowing for a very clean and healthy space. 08/19/2015
